How to uninstall an application(msi) during install?

The solution is very simple. Since A, from what I can see is a MSI package you can simply go to Upgrades page in Advanced Installer, for project B, and use the "New" button to add the MSI for app A to the list.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
